COLLAPSIBLE TUBE.

Specification of Letters Patent.

Patented Mar. 23, 1920.

Application filed December 23, 1918. Serial No. 237,985.

To all whom it may concern:

Be it known that I, CLARENCE J. BEAT'EY, a citizen of the United States, residing at Racine, in the county of Racine and State of Wisconsin, haveinvented certain new and useful Improvements in Collapsible Tubes, of which the following is a specification.

The present invention comprehends generally improvements in that class of inventions known as dispensing and more particularly relates to a collapsible tube.

It is the primary aim and object of the present invention to provide a container or tube for tooth paste, shaving or cold cream, Vaseline, catarrhal jellies, influenza balms, et cetera, wherein the spout or mouth of the container is extended from the attaching portion thereof so that the contents when being dispensed will not contact with such attaching or threaded portion upon wliich germs gather, whereby to prevent germs touching the brush or face at thetime the paste or cream is applied.

More particularly the present invention consists in the provision of a container of the above mentioned character wherein there is employed in connection with the usual' container body a spout of non-corrosive material which is fitted within the body and a closure cap designed to be arranged about the projecting portion of the spout and detachably engaged with the body of the container for protecting the contents of the container.

Among the other aims and objects of the present invention may be recited the provision of a device of the above mentioned character which is sanitary and wherein the number of parts are comparatively few, the construction simple, the cost of production low and the efficiency and durability high.

Other objects, as well as the nature, characteristic features and scope of this -inven tion will be more readily apparent from the following description taken in connection with the accompanying drawings and pointed out in the claims, forming a part of this pecification.

The invention is clearly illustrated in the accompanying drawmgs, 1n which Figure 1, s a vertical cross sectional view showing the improved form of container ,closure,

Fig. 2 is a transverse sectional view taken on the line 22 of Fig. 1 in the direction in which the arrows point,

Fig. 3 is a vertical sectional view of an other form of the invention,

Fig. 4 is a vertical central section of another form of the invention,

Fig. 5' is a cross section on line 5-5 of Fig. 4, and

Fig. 6 is a vertical section of still another form of the invention.

Similar characters of reference are employed in all of the above views to indicate corresponding parts.

Referring now, more particularly, to the accompanying drawings, there is provided a container body 1 which may be of metal and of the flexible type which can be rolled up for the ejecting of the contents. A neck 2 issues from one end of the body and is formed with exterior screw threads 3 for a purpose that will become apparent.

With a view toward providing improved sanitary closure for the container, a spout 4 preferably formed of non-corrosive or non-oxidizing material such as glass, celluloid, bone, amber, china, et cetera, is fitted within the neck and is preferablycylindrical for frictionally engaging the inner surface of the neck while the bore 5 is rectangular in cross section, the inner end of the tube being flared as at 6 to correspond to the curvature of the body at the juncture of the neck while the extreme inner end of the spout is formed with a bead 7 which is seated within an annular groove 8 in the body 1. This arrangement serves to prevent accidental movement of the tube or spout with respect to the container. A closure cap 9 which is desirably of cylindrical configuration is now employed, the inner surface near the free edge being'formed with screw threads 10xwhich engage the threads 3 when the cap is arranged about the spout or that portion thereof which projects beyond the neck. The cap is also provided on its inner surface and I immediately adjacent the under surface of the top with an annular groove 11 in which feature to practice, the body 13 of the container isformed at its outer edge with an inturned flange 14. The spout 15 has its extreme outer portion shaped correspondingly to the spout of the preferred form and in addition is provided near its inner end with exterior screw threads 16 while this inner end is also enlarged as at 17 and formed with a depending flange 18 which is in turn provided in its outer surface with an annular groove 19 designed to receive the annular flange 1 1 of the body of the container. A-closure cap 20 has a sealing disk 21 mounted in the inner end thereof and, this cap and disk are of a construction similar to the preferred form so that when engaged directly on the inner portion of the spout the inner surface is spaced from the outer surface of the extreme outer portion of the spout so that germs will not accumulate thereon.

In Figs. ,4 and 5 there is shown another form of the invention which in the present instance may be said to consist of a container body 22 formed with an integral neck 23 having exterior threads 24 for a purpose that will appear. Integral with and projecting longitudinally from the outer edge of the neck is an elongated spout 25 of a tubular configuration in cross section, the inner surface of the spout being arranged in alinement with the inner surface of the neck 23 while the outer surface terminates short of the threads 24 as shown in Fig. 4 so as to be positioned in spaced relation to the inner surface of the cylindrical closure cap 26 which is detachably engaged with the threads 24 and which carries a sealing disk 27 for coacting with the mouth of the spout, the construction of the cap 26 and disk 27 being similar to the construction of the same parts in the form shown in Figs. 1 and 3. This form of tube is especially adapted to contain catarrh jellies or influenza balms, the point being that the spout is extended from the threaded or shank portions upon which latter portion germs accumulate, whereby to prevent the germs from infecting the brush or paste at the time the paste or cream is dispensed and applied.

The form of the invention shown in Fig. 6 is substantially the same as that shown in Fig. l with the exception that the spout 28 which is of non-corrosive material is extended a reater distance from the outer end of the me i 29 and instead of being anchored a bead 30 and seated in an annular groove 31 at the inner surface and near the outer edge of the neck. The neck of course is threaded as at 32 to detacha-bly receive the sealing disk and closure cap 33.

It is believed in view of the foregoing description that a further detailed description of the operation of the invention is entirely unnecessary. Likewise, it is believed that the advantages of the invention will be readily apparent. However, attention is respectfully directed to the fact that both the spouts I and 16 are formed of non-corrosive or non-oxidizing material while the closure caps are designed to be spaced from the outer portion or mouths of the spout so that poisons will not iaccumulate on the spout even though the cap be formed of metal.

Still further embodiments of the invention than those herein especially defined may be resorted to as conditions or preference may dictate, as may be in keeping with the hereto appended claims.

Having thus fully described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

1. A device of the character described comprising a hollow body, a neck carried thereby provided with a reduced outer portion forming a spout, a cap removably fitted upon the inner portion of the neck, and a sealing element arranged in the closed terminal of the cap engaging the open end of the spout, said reduced portion of the neck being disposed in concentrically spaced relation to the contiguous portion of the cap and the latter being maintained in spaced relation to the terminal of the neck by the sealing element.

2. A device of the character described comprising a hollow body, a. neck carried thereby provided with a reduced outer end, screw threads carried by the inner relatively large portion of the neck, a cap provided at one terminal with internal screw threads fitting the threaded portion of the neck, said neck being disposed in concentrically spaced relation to the cap, and a sealing element secured in the closed terminal of the cap and preventing contact of the material of the cap with the reduced terminal of the neck.

In testimony whereof, I afiix my signature hereto.

CLARENCE J. BEATTY.
